| Abstract | ||||
| This research was conducted during two baffling agricultural seasons of 2016/2017 and 2017/2018 at Kaha Vegetables Research Farm, Hort. Research Institute., Agriculture Research Center, Egypt to study the stimulation of the potato plant's cv. Picasso ability to tolerance low temperature and improving tubers yield and qualities through appropriate agricultural practices in parallel with the addition of adequate fertilizers of NPK plus micro-nutrients spraying and some anti-stress substances. The experiment included eight treatments consisting of two fertilization treatments in main plots and four anti-stress as sub plots. The results indicate that treating plants with a suggested nutrients program, along with foliar spraying with some minor elements and some anti-stress, such as selenium plus vitamin C or vitamin E in addition to a commercial anti-stress compound led to stimulating the plant's ability to tolerance low temperature and improved plant growth. Anti-stress commercial compound at 100 ppm concentration exhibited the significant superiority in most of vegetative growth traits (stem length - average number of both stems and leaves as well as fresh weight of stems and leaves and reflected so positively on the total yield of tubers, quality characteristics and the percentage of tubers starch. Also, results indicate that the remainder of the treatments recorded significant differences and gave values that reached the level of significance in most of the characteristics of vegetative growth and yield and its components, compared to the control treatment, which recorded the lowest values of all studied traits. Conclusively, the recommended program for planting in the off-season growing cycles will give the highest yield due to the balanced fertilization and anti-stress /anti-oxidants, as well as, in the same time will take care of the tubers quality. So that, the tubers yield will gain the highest values of economic competition in locally and international markets and to contribute as a good source of hard currency for Egypt. | ||||
